I guess I just wanted to make sure I had read enough of it to be able to feel minimally comfortable with my understanding of how DCO works. As long as we are fine with the approach, and enough of us have an understanding of what the DCO path means, I'm fine either way. > > I understand the risks that somebody might claim they hold the copyright > when they don't.
